Witherspoon has 3x as many wins over top ten Heavyweights as Haye & Chageav have combined.

The real question is whether or not Vitali even rates above Witherspoon.

Think about it.

They have about the same # of wins over top ten Heavyweights. Only Witherspoon's wins are of much better quality.

Also, Witherspoon's showing in his fight against a ATG Heavyweight in his prime was vastly superior to Vitali's showing when he fought an ATG Heavyweight, who was past his prime, inactive and out of shape.
